Replit View Counter

As a casual browser of this site, you may have noticed the section at the bottom of each page showing a word count, estimated reading time, and view counter.

The word count and reading time are generated by Hugo, but Hugo can’t track view counts by nature; it’s a static site generator, only able to smash bits of HTML together at lightspeed.

I had to implement a backend to handle this dynamic page data.

At first, I had great ambitions for a set of services to connect all my sites, and started a Django project called Auxilliary Website Services. The original intention was to bring user accounts, bookmarking, comments, and other gizmos to,,, etc. Unfortunately, there just hasn’t been a real need or time to do this, and users have had to wait upwards of thirty seconds for the Django view-counter to boot. In addition, I have added recently, which was crazy easy to set up and provides the perfect authentication method (Github login) for a corporate-facing tech site.

To solve this problem, I decided to take half an hour to rewrite the view-counter in, an integrated code editor and PaaS. Using the included key-value database, it’d be super easy to associate numbers with website paths.

…and that’s exactly what I did. Here’s the source code. Scroll to the end of the page to see the view counter in action.

from replit import db

app = Bottle()

#this is the main page
def index():
    return '<pre>RCF Analytics Mk</pre>'

#this can only be accesed with a post request (visiting in browser will return 405 Method Not Allowed error)
def post_request_only():
    print("Analytics POST, collecting data...")
    path: str = str(request.json.get('page_url'))
    site: str = str(request.headers['origin'])
    if not path or not site:
        return dumps({})

    # ReplIT Database HATES '/', so remove 'em
    key: str = f"{site}-{path}".replace('/', ' ').strip().replace(' ', '-')
    print(f"key: {key}")
        views = db[key]
        db[key] = views + 1
        return dumps({'page_views': views + 1})
    except KeyError:
        print("KeyError, adding...")
        db[key] = 1
        return dumps({'page_views': 1})

#A 404 page if the url doesn't exist
def error404(error):
    return (
        "oops! the page you were looked for isn't here. <a href='/'>Return Home?</a>"

    port=1234)  #this starts the webpage. any code after this line won't be run

Page views are cached in Session Storage to prevent multiple views during a single session from ratcheting up the view count and inflating the popularity of the page.

All that said, this is certainly the most privacy-respecting way to implement something like a page view counter, and a good first step towards rolling your own page analytics.
